valid conversion results. The differential common-mode
range is defined as:
In addition to the common-mode input voltage limitations,
each individual analog input must be limited to ±16.5V
with respect to AGND1.

The range-select bits R[2:0] in the analog input config-
uration bytes determine the full-scale range for the cor-
responding channel (Tables 2 and 6). Figures 9, 10,
and 11 show the valid analog input voltage ranges for
the MAX1300/MAX1301 when operating with FSR =
(±3 x V
respectively. The shaded area contains the valid com-
mon-mode voltage ranges that support the entire FSR.
